PAC LV is a premium grade purified low viscosity, water soluble polyanionic cellulose, designed to reduce API filtration rate to water-based drilling fluids. PAC LV can meet requirement of M-I SWACO, HALLIBURTON, BAKER HUGHES, Chevron and the API 13A Section 17 Specification.

Advantages

• Effective in fresh water, salt water, and brine-based fluids
• Controls fluid loss
• Inhibits hydratable, swelling shale
• Environmentally compatible
• Does not require a bactericide
• Is stable at temperatures up to 300°F /149°C

Applications

• Very effective filtration controller in non-dispersed systems
• Minimal viscosity contribution
• Resistant to micro-bacterial attack without biocides
• Applicable over a wide range of fluid types
• Contributes to shale stabilization

Recommended Treatment

Add PAC-LV in concentration of 0.7-1.9lb/bbl (0-5.5 kg/m³) to any system. Mix slowly through a jet mixer or sift slowly into the vortex of a high-speed stirrer.
